Experiment: Boiling 500 ml of water and collecting the vapor
In this experiment, 500 ml of water in a glass X is heated until it completely vaporizes. The objective of the experiment is to determine the amount of water vapor collected in glass Y.
Procedure:
- Take a glass X and pour 500 ml of water into it.
- Place the glass on a heat source, such as a Bunsen burner or a stove.
- Apply heat to the glass and continue heating until all the water inside evaporates and turns into vapor.
- Collect the vapor using glass Y by placing it above the glass X.
- Weigh the glass Y before and after the experiment to determine the amount of water vapor collected.
Explanation:
When heat is applied to the glass X containing water, the water molecules gain energy and start moving faster. As a result, the water molecules at the surface of the water gain enough energy to overcome the attractive forces between them and escape into the air as water vapor. This process is known as evaporation.
The water vapor rises and condenses on the inner surface of glass Y, which is cooler than the vapor. This condensation process converts the water vapor back into liquid water, which is collected in glass Y.
Amount of water collected in glass Y:
The amount of water collected in glass Y will be approximately equal to the amount of water that was initially present in glass X. This is because during evaporation, only the water molecules escape into the air as vapor, while impurities and other substances are left behind in the glass X. Therefore, once the vapor condenses in glass Y, it forms pure water.
However, it is important to note that some loss of water may occur due to factors such as evaporation during the experiment, incomplete condensation, or leakage. These factors may cause a slight difference in the amount of water collected in glass Y compared to the initial amount of water in glass X.
To obtain an accurate measurement of the amount of water collected in glass Y, it is necessary to weigh the glass Y before and after the experiment. The difference in weight will give the approximate amount of water collected in glass Y.
